Celebrating thirty years of virtual outcrops: status and perspectives
1Virtual Outcrop Geology Group, Bergen, Norway; 2University of Aberdeen, UK
Thirty years ago, scientists from the Technical University of Denmark and University of Bergen published 3D outcrop acquisition and processing methods for large-scale vertical cliff sections in Greenland (Dueholm & Olsen, 1993), thus laying out a pathway to today’s state-of-the-art in high resolution virtual outcrop modelling. Although the photogrammetric methods employed were based on film cameras and early digital processing, the authors successfully created stereoscopic outcrop models that could be used for accurate measurement of cross sections, channel bodies, and derived parameters such as net-to-gross ratio. Fast forward to today, and virtual outcrop modelling has evolved rapidly, spanning early work using laser scanning, integration with hyperspectral imaging, and the full-circle return to photogrammetry. The latter has brought about a paradigm shift in field geoscience, driven by lightweight digital cameras, drone platforms, and powerful computing hardware combined with automated image matching and point cloud generation algorithms. This has empowered geologists and geoscientists to quickly – and at low cost – acquire and process high resolution, accurate 3D models for detailed analysis. Over the last five years, and particularly through the COVID-19 pandemic, virtual outcrop models have been increasingly used for “soft” purposes, in education and training, for introducing a wide range of different geological features and concepts that may be difficult to access in a single field area, or as the basis for integrating a range of geospatial, field and subsurface data. In this contribution we will explore the status and impact of virtual outcrops and offer thoughts on future perspectives.

LiquidEarth: Integrating Rapid 3D Geological Modeling in Cross-Platform Mixed Reality
1Terranigma Solutions GmbH, Germany; 2Computational Geoscience, Geothermics and Reservoir Geophysics, RWTH Aachen University, Germany
Virtual and mixed reality technologies are reaching maturity for both professional and consumer applications, offering not only stereoscopic 3D visualization environments but also novel user interfaces with more immersive experiences of interacting with 3D content. Geosciences, which inherently deal with 3D complexities, can greatly benefit from these advancements. However, the potential benefits remain largely untapped for professional applications. Recent developments are bringing 3D geodata visualization with collaboration into virtual spaces. Nonetheless, the actual steps of 3D geological model creation and modification remain predominantly limited to workstation computers and 2D displays.
Addressing these limitations, we present LiquidEarth, a software solution that integrates rapid geomodeling with immersive mixed-reality environments. Utilizing a cloud-accelerated implicit modeling algorithm, LiquidEarth offers a dynamic experience of creating and updating 3D geological models in virtual spaces with real-time feedback. Cross-platform compatibility makes the solution device-agnostic, facilitating adoption in various geoscience applications and scenarios, including fieldwork.
The software combines features such as immersive visualization, real-time collaboration, field connectivity, workflow connectors, and flexible export options to create an integrated and versatile tool, making it ideal for geoscientific work in industry, research, and education. This holistic approach bridges the gap between immersive visualization of geological data and geological modeling, enabling geoscientists to harness the full potential of mixed reality technologies.
LiquidEarth signifies a substantial, yet initial, step towards the future of geomodeling by transcending traditional constraints. Its objective is to augment the geoscientific expert's ability to analyze and comprehend intricate geological 3D complexities while promoting the development of insightful conclusions.

Investigating the impact of differential biogenic carbonate production on carbonate system geometries through stratigraphic forward modelling: The Llucmajor example.
1University of Potsdam; 2Fraunhofer IEG
The geometry of carbonate systems reflects the interaction of several factors. Although efforts have been made at investigating the controls on biogenic carbonate system evolution, the impact of the interaction of different carbonate producing biotas is still not fully understood. In this study, we developed a 4D stratigraphic forward models (SFM) of the Miocene Llucmajor platform coupled with sensitivity analysis to examine the effect on platform geometry of changes of the dominant biotic production in the oligophotic and euphotic zones. Our results indicate that the geometry of the platform is impacted by a complex interaction between carbonate production rates, variations in bathymetry, and changes in accommodation. Progradation in the platform model is mainly controlled by oligophotic production of rhodalgal sediments during the lowstands. This study also shows that platform geometry and internal architecture is significantly impacted by the interaction of the predominant carbonate producing biotas. The input parameters for this study are based on well-understood Miocene carbonate biotas with characteristic euphotic, oligophotic and photo-independent carbonate production in which it is essential to explicitly model each carbonate producing class within the simulation run and not averaged with a single carbonate production-depth profile. This distinction is particularly crucial for subsurface exploration studies that rely on stratigraphic forward models, where the overall platform geometry may be approximated through calibration runs and constrained by seismic surveys and wellbores. However, the internal architecture could be over-simplified, without an in-depth understanding of the target carbonate system such as is provided by this study.

Digital methods for the planning and construction of geothermal plants
Bauer AG, Germany
Digitalisation helps to improve planning, make processes more transparent, save resources and counteract the staff shortages that will become even greater in the future.
BAUER Resources GmbH has been using the BIM methodology for over a decade, and for some years now processes in construction site operations and planning have been digitally supported.
With the help of drones, apps on mobile devices and sensors, linked with intelligent systems, execution and planning are being taken to a new level of detail, transparency and speed.
The detailed planning and execution of geothermal projects including geologie and hydrologie with digital support will be presented. Implementations in BIM with automation and other digital techniques (including real-time data from the construction site) which leads to a digital twin will be presented.
